Researching Open Educational Practices (OEP)

MedienPädagogik: Zeitschrift für Theorie und Praxis der Medienbildung, 2018
Offenheit an Hochschulen wird derzeit vor dem Hintergrund der Idee einer ‹Open Education› diskutiert, welche auf die Etablierung von Open Educational Practices (OEP) und Integration von Open Educational Resources (OER) im Lehr-/Lernalltag zielt.

Millisecond Spin Relaxation Times of Distinct Electron and Hole Subensembles in MAxFA1−xPbI3 Perovskite Crystals

Advanced Science, EarlyView.
Mixed‐cation MAx${\rm MA}_x$ FA1−x${\rm FA}_{1-x}$ PbI3${\rm PbI}_3$ perovskite crystals reveal multiple discrete electron and hole spin subensembles associated with distinct localization environments. Optically detected magnetic resonance combined with resonant spin inertia uncovers carriers spin relaxation times reaching 2 ms and identifies nuclear ...

Chlorine‐Free Depolymerization of Commercial PMMA via Oxygen‐Centered Radicals

Angewandte Chemie, EarlyView.
A new chlorine‐free photothermal method enables sustainable recycling of plastics with C–C backbones under mild conditions. Driven by an oxygen‐centered radical pathway with ppm levels of anthraquinone catalyst, it eliminates hazardous chlorinated solvents, achieving an impressive 97% depolymerization conversion.

Non‐Destructive, Reference‐Free Quantitative Analysis of TaOx Memristive Devices Using Soft X‐Ray Radiation

Advanced Electronic Materials, EarlyView.
A non‐destructive, quantitative approach has been developed to explore the nanoscale dynamics of TaOx‐based memristive devices. The utilization of nano‐X‐ray fluorescence analysis enables the direct probing of spatially resolved elemental distributions, including those present in buried layers, that are critical for the resistive switching.

Analog Weight Update Rule in Ferroelectric Hafnia, Using picoJoule Programming Pulses

Advanced Electronic Materials, EarlyView.
Resistive, ferroelectric synaptic weights based on BEOL‐compatible hafnia/zirconia nanolaminates are fabricated. Lateral downscaling the devices below 10 µm2 enables 20 ns programming with electrical pulses, dissipating ≤ 3 pJ. Experimental results show that final conductance state is set by pulse amplitude, and is largely independent of the initial ...

Degradable Alternating Copolymers With Strained Cyclobutane Backbones via Photocontrolled RAFT Polymerization

Angewandte Chemie, EarlyView.
A photocontrolled RAFT strategy enables the alternating copolymerization of 1,3‐disubstituted bicyclo[1.1.0]butanes with electron‐deficient comonomers, affording well‐defined copolymers bearing strained cyclobutane backbones. A high degree of alternation, tunable molecular weights, and excellent end‐group fidelity are achieved through a CTA‐mediated ...

Alumni von Hochschulen als heterogene Zielgruppe akademischer Weiterbildung

Zeitschrift Hochschule und Weiterbildung, 2017
Alumni sind eine bedeutende Zielgruppe der Hochschulen für ihre Weiterbildungsangebote. Ein Großteil der Alumni bleibt nach dem Studium in der Hochschulregion wohnhaft, oder nimmt  im  näheren  Umfeld  der  Hochschule  eine  Erwerbstätigkeit auf.

Structured sorbents for Direct Air Capture: The impact of materials and chemicals on performance

AIChE Journal, EarlyView.
Abstract Structured sorbents can efficiently process large air volumes required for Direct Air Capture (DAC), but their broad implementation is limited by challenges in producing reproducible and homogeneous materials. This work presents a robust procedure to graft amines onto monolithic sorbents and systematically investigates how CO2$$ {\mathrm{CO ...
